Here is my model airplane project. It has been almost 3 months in the making. Having tested countless designs to achieve the lightest and strongest possible construction, this is my final build. It was designed as a complete project incorporating motor and servo mountings, push rods and control horn locations, with interchangeable engine cowling at the firewall. All control surfaces, rudder and elevators are pre-slotted for hinge insertions and can be glued in place with super glue. The air craft is a typical high wing Clark Y-wing section with good dihedral and lots of wing area. This is an easy-to-fly trainer model, not representing any scale design of any kind. It is a popular design for anybody starting out, irrespective that it is a 3d printing exercise in RC modeling. The whole plane is constructed in modules no larger than your Makerbot-type 3d printer. The proto type here in the pictures was created on so most printers with a compatible print area will suffice. Instructions Instructions for printing are as follows:- To achieve the weight required the main thing to remember is to keep the fuselage, wings and tail planes set to hollow and extrude only 1 layer into the perimeter. Keep the extrusion ratio down as low as possible. Other parts such as bulk heads and servo mountings can be solid. All STL files are presented on opening in their recommended printing orientation. I have included a photo tutorial that will help with the assembly procedure. My plane was manufactured in ABS and then glued together with acetone and supper glue. The hinging of all movable surfaces such as ailerons, elevators and rudders utilize standard CA model plane hinges no wider than 14 mm. Also see photos for servo types and other RC equipment recommended. G-code settings name = Yellow PAF ; layer_thickness_mm = 0.25 ; extrusion_width_mm = 0.5 ; num_loops = 1 ; skin_thickness_mm = 0 ; infilldensity 0 ; stacked_layers = 1 ; support_density = 0 ; raft_mode = 0 This is an experimental exercise so any improvements and ideas will be very welcome. Thank you.
